I agree that it's a case by case basis. I just fear that some costumes may not be given a fair shot before being given the Hollywood revamp treatment.

You've gotta look at it from a practical perspective though, comics by their very nature are an exaggeration, it may seem simple on paper, but there are things to consider like movement, like logistics, like comfort, like how it looks on camera, like how to not make it look ridiculous, there's a lot of things to take into consideration which is something a comic doesn't have to do. On top of that you've got the director's interpretation and how he/she sees the character. It's the nature of the medium, these are adaptations after all, not comics brought to life, because that's all they can ever be.
